The figure shows a rigid structure consisting of a circular hoop of radius R and mass m, and a square made of four thin bars, each of length R and mass m. The rigid structure rotates at a constant speed about a vertical axis, with a period of rotation of 3.5 s. If R = 1.0 m and m = 3.9 kg, calculate the angular momentum about that axis.

Figure shows a rigid structure consisting of a circular hoop of radius R and mass M, and a square made of four thin bars, each of length R and mass M. The rigid structure rotates at a constant speed about a vertical axis, with a period of rotation of 2 s. Assume R = 0.2 m and M = 3 kg. Which is the closest to the the angular momentum about that axis?

The figure shows a rigid assembly of a thin hoop (of mass m = 0.29 kg and radius R = 0.15 m) and a thin radial rod (of length L = 2R and also of mass m = 0.29 kg). The assembly is upright, but we nudge it so that it rotates around a horizontal axis in the plane of the rod and hoop, through the lower end of the rod. Assuming that the energy given to the assembly in the nudge is negligible, what is the assembly's angular speed about the rotation axis when it passes through the upside-down (inverted) orientation?

Q.6. A small point-like piece of clay with mass m = 200 g is traveling at a constant velocity v→0 = (30 m/s) î towards a stationary cylindrical hoop of mass M = 2000 g and radius R = 50 cm that is free to rotate about its central axis which is at the center of the zy-plane. Before sticking to the hoop, the clay is traveling along a horizontal line a distance d = 23 R. The clay impacts and sticks to the hoop at point A. a. What is the angular momentum of the system L → 0 before the collision about the origin? (include unit vector direction) b. What is the moment of inertia of the system after the clay sticks to the rod? c. Find the angular speed ω just after the collision. d. What is the kinetic energy of the system just after the collision? e. At what vertical height y does point A momentarily stop?
